When using beeline to connect to a kerberized HiveServer2 it still prompts for a username and password that aren't used. It should be changed to not prompt when using Kerberos:
Hive conf includes (as concisely shown by set):
I can't see how to demonstrate in HQL session that I am not connected as "wronguser" (which obviously doesn't exist either locally or as a Kerberos principal or account in my LDAP directory), so I've raised another ticket for that
HIVE-9143, but it should be clear given I specifed a non-existent user and a completely blank password just hitting enter that it's not using those credentials. Same happens with <enter>, <enter> for both username and password.
